I am using gtx 10w-30 in my wifes saturn L-300 3.0 liter 24 valve V-6. Seems this motor is a little hard on oil- Used amsoil for a six month run and experienced some shearing back to 20 weight, though my wife makes very short trips in both winter and summer. Nothing against amsoil just wanted to try a conventional oil with a decent reputation. I will be doing UOA in a few weeks due to the severe nature of the cars use. Any thoughts on castrol gtx. I am trying to find a good oil with good protecton at the best price. My wife thinks I have a sickness with this motor oil thing- oh well I enjoy every minute. This is a great forum.
